Performing Actions on Replicated Volumes

To perform actions on a replicated volume resource using the LifeKeeper GUI, right-click on the replicated volume resource and select the action you wish to perform from the context menu. If you have the Properties Panel enabled (View->Properties Panel), the resource toolbar will be displayed for the selected volume.

Action

Icon

Meaning

Select Target

Select the target system to which the action should be applied.

Pause Mirror

Select Pause Mirror to temporarily stop the data from being mirrored. A partial resync will be performed when you click Continue to un-pause the mirror. After pausing a mirror, it is possible to unlock the target volume using the Unlock Target action.

Continue Mirror/Lock Target

To continue a mirror after the mirror has been paused, select the Continue/Lock Target action. This un-pauses the mirror, re-locks the target volume (if unlocked) and resumes the mirroring process.

While pause temporarily stops the writes from being mirrored, the writes are recorded during the pause interval. When the mirror is resumed, the recorded writes are sent to the target volume and the mirror is automatically re-synchronized (partial resync).

Unlock Target

To unlock the target volume of a mirror, select the Unlock Target action. This pauses the mirror (if not already paused) and unlocks the mirrored volume on the target system. This allows read/write access to the data on the volume.

Continue Mirror will relock the target volume, perform a partial resync and resume the mirroring process.

Warning: Any writes to the target volume while unlocked are lost when the mirror is resynchronized.

Break Mirror/Unlock Target

Breaking a mirror discontinues the mirror for the selected volumes and unlocks the target volume but does not remove the mirror from the volume list. A full resync must be performed in order to re-establish the mirror after a Break Mirror/Unlock Target action.

Warning: Any writes to the target volume while unlocked are lost when the mirror is resynchronized.

Resync Mirror/Lock Target

To re-establish a broken mirror, select Resync Mirror/Lock Target action. A full resync will be performed.
